Question
An Airbus A380-800 passanger airplane is
cruising at constant altitude on a straight line
with a constant speed. The total surface area
of the two wings is 395 m². The average
speed of the air just below the wings is 248
m/s, and it is 278 m/s just above the surface
of the wings. What is the mass of the
airplane? The average density of the air
around the airplane is pair = 1.05 kg/m³.
